Hi hope you're great..
I wanna know about the origin of T and B cells, like where do they come from? Other than bone marrow, I'd be glad if you share some references that can help.

باختصار:
T-cells after their initial differentiation in the bone marrow, they go to the thymus to fully differenciate and become functional then get distributed to the rest of the body.

B-cells mature in the bone marrow then travel to the spleen to fully differentiate and then they are distributed to the rest of the body.

streptococcal toxic shock syndrome typically has a recognizable site of pyogenic inflammation and blood cultures are often positive, whereas staphylococcal toxic shock syndrome typically has neither a site of pyogenic inflammation nor positive blood cultures.

Why do we vaccinate splenectomy patients against S. pneumonia and tetanus?

Because after splenectomy, the levels of antibody are preserved but there is a loss of memory B cells against pneumococcus and tetanus, and the loss of marginal zone monocytes deputed to immunological defense from capsulated bacteria.
This results in an increased susceptibility to pneumococcal infections, and to gram-positive infections in general.
